Metalife, NP3+, Cerakote.....
My first choice for the service you may want would be Metalife;
www.mahovskysmetalife.com . It has a grey/nickel surface color that's non reflective. The specs are great. Gun-writer & tactics instructor;
Chuck Taylor gives it high praise.
A few forum members say it works very well. I like the shop turn-around & the prices. I may get my Glock 21 .45acp upper treated with Metalife for use on security posts. I live & work in hot, humid areas & sometimes near marine/beach environments.
Other top picks include Robar's NP3/NP3 plus,
www.robarguns.com . It's not cheap and can take several months to get your firearm back but the process it great. I've owned 02 Beretta 96D .40 pistols with NP3 & Im very impressed with Robar's quality. Scuffs, nicks & holster wear aren't a big problem with NP3.
Rocky Mountain Arms/Bearcoat is a good after market process. It comes in a dull grey, Ti and "stainless" type color. Bearcoat is also a durable, high quality format. Hunting guides, cops & spec ops(snipers) use Bearcoat.
Finally, a new source I'm impressed with but have not purchased is the Cerakote designs from MI's
www.blowndeadline.net . The shop offers different Cerakote colors/styles & they can add the new
armor-clear process for improved wear/scuff/mar protection. Cerakote shops are now all over the USA, check to see if they warranty the services(like Blowndeadline does
), make sure they are
authorized & offer the extra armor-clear process. It's not mandated, but Id want it on my duty weapon or CCW gun.

PS; if it's a N frame .41 you might consider Mag-Na-Port porting, then have the gunsmiths add Mag-Na-Port's company surface treatment. See the website for prices & services. I heard & read a few + reviews.
